Select the INCORRECTLY spelt word.

Correct — C. The word should be beginning: begin + -ing.

Begin ends consonant-vowel-consonant and is stressed on that last syllable, so the rule doubles the final consonant — the n. The g is untouched.

The paper prints Beggining, which doubles the wrong letter and leaves the right one single. Cemetery, occurrence and interrupt are all spelt correctly as printed, so option (c) is the misspelling.

Why the others are wrong

• (a)
  Cemetery — Cemetery is correct as printed. Its own trap is the vowel run — three e's and no a, so cemetary is the misspelling — but nothing is wrong with the option here.
• (b)
  Occurrence — Occurrence is correct as printed: double c, double r and the ending -ence. It is a word candidates often get wrong, so it draws the eye, but it is right.
• (d)
  Interrupt — Interrupt is correct: the prefix inter- meeting the root -rupt gives the doubled r, and the word ends in a single t.

English doubles a final consonant before -ing when the word ends consonant-vowel-consonant and the stress falls on that final syllable.

beGIN is stressed on -gin, so the n doubles: beginning
ENter is stressed on en-, so nothing doubles: entering

Beggining breaks the rule at both ends. It doubles a consonant the rule does not reach, and it leaves single the consonant the rule does reach.

Key facts

• Beginning doubles the n: begin + -ing, with the stress on the final syllable of begin.
• Cemetery is spelt with three e's and no a.
• Occurrence takes a double c, a double r and the suffix -ence.
• Interrupt has a doubled r from inter- plus -rupt and a single final t.

Common traps

• Marking occurrence wrong on sight because it looks over-doubled
• Applying the doubling rule to words stressed on an earlier syllable, which produces openning or offerring
• Checking only the first half of each word, where beggining already looks plausible
